According to the Toddfather himself, it is canon and part of the main series, saying the main series and Hellspawn would sync up.
I had this exact question and Todd McFarlane printed it in the back of Spawn #243.

Here's a link to his answer. https://imgur.com/gallery/6jYRMvb

Posted this is the SpawnWorld Discussion board too. So I just discovered this article that went over several announcements McFarlane made in regards to the Spawniverse. (Just for the record, issue #283 is the most recent issue.) 1) Spawn will finally reach its long-awaited landmark issue: #301! Maki...

All Spawn does in Savage Dragon #30 is tell The Dragon his backstory (being tricked by Malbolgia and finding out he'd been kept in Hell 5 years), he tells Dragon they are in Hell, and then Dragon's villain The Fiend shows up and teleports Spawn out of there.

Oct 11, 2015 So I'm not sure what's going on with the creative team Todd had with Jonboy and Jenkins. It seemed like everything was going smoothly and the story is starting to really pick up. But the other day I read an article saying Jenkins had left on issue #254 and that Todd would be writing wit...

This really bums me out. I was so excited to see what Brian would bring to the table. It sounded like something massive was going to happen if he was removed for creative differences. Another Armageddon sized event? I guess we'll never know. Hopefully they announce a new writer soon! I love Todd as ...

I deleted the original "chronological" timeline and replaced it with the ultimate reading order. Reading the series chronologically isn't all it's cracked up to be. There's references to characters, places, and events that the reader wouldn't understand. This is the BEST WAY to read Spawn ...

I saw this on Todd's Facebook page and I flipped out, thinking it was from the ACTUAL movie he has in the works. :lol: It's really well done. I'm pretty sure the "Witch" he was talking to may have been Nyx. I've been waiting for her to make a comeback in the comics. She was such a great ch...

UPDATE: 7/7/14 In regards to if the 16 issue Hellspawn series is canon or not, I sent a message to Mr. McFarlane himself and he answered my question and printed it in the letters page of Spawn #243 in the third column. Basically, yes it is, even though the ending is a bit at odds with the main serie...

Or this one on top. I personally like this one.
